ABSTRACT:
A pressure compensated, hermetically sealed transmission system is described which includes, basically, a hermetic rotary coupling. Rotary motion is applied through a casing, wherein a cylindrically shaped input shaft having a circular inner bearing race affixed to one end is coupled to a generally spherical shaped wobble plate by means of roller or ball bearings. In similar fashion, an output shaft is similarly coupled to the spherical shaped wobble plate at the opposite end. The inner races of the shafts are positioned at an angle and located eccentrically from the respective shaft center line. Both shafts are supported at their outer ends by combination journal thrust bearings, which are coupled to the main casing. The wobble plate is prevented from rotating about the common axis of the two shafts. Thus, as one shaft rotates, the wobble plate rocks, due to ball bearing action, but does not rotate. Likewise, due to the bearing action, as the wobble plate rocks the output shaft rotates. Overall, a system is described which provides for equalization of pressure across imperforate flexible membranes which increase the reliability of the imperforate flexible membranes by providing for pressure feedback through a loop to insure equal pressure on both sides of the imperforate flexable membranes so as to increase the integrity thereof.
